PUMPING APPARATUS FOR CSTERNS.

Specification of Letters Patent.

Patented May 23, 1922.

To all whom t may concer-n.'

Be it known that THEoDoRE SARLLS, a citizen of the United States, residino' at Sanders, in the county oi Carroll and patate ot Kentucky, have invented certain new and useful improvements in Pumping Apparatus for Cisterns, of which the following is a specification.

This invention relates to pumping devices and has special reference to pumping apparatus for cisterns and other like reser` voirs.

One important object ot' the invention is to improve and simplify the general con` struction of devices ofthis character.

A second important object of the inven tion is to provide an improved pumping device for cisterns wherein the discharge oi' water will be effected by compressed air so that proper discharge may be obtained irrespective of the depth ot the cistern.

A third important object of the invention is the provision of improved means for discharging water from a cistern wherein the water to be discharged may be kept under air pressure so that the mere opening of valve will permit water to be discharged.

lith the above and other objects in view as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations orn parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

The ligure is a section through cistern showing the .improved pumping apparatus 1n position.

In the embodiments of the invention herein illustrated there is disclosed a cistern or reservoir 10 of ordinary construction and provided with the usual lid or cover 11. Located within this cistern or reservoir and reaching from the bottom thereof to point near the top ot the cistern is a discharge tank 12. This tank is closed at the top and is only open to the liquid 13 in the cistern at the bottom, an inwardly opening check valve 14 beingprovided at this point for the purpose oi' allowing free flow ot' water into the cylinder 11 and of preventing water Jfrom flowing out oi' that cylinder. Located in convenient relation to the cistern is an air pump 15 of any preferred type, the pump here shown being such as is usually employed in pumping air into automobile tires. This pump is connected by flexible tubing 16 through a check valve 17 to a pipe line 18. The check valve 17 opens away from the pump so that any air 'forced into the pipe line cannot i'low back as the pump handle is lifted. Connected to the pipe line 18 is a pressure 19.

This pipe line 18 is continued down through the cistern and enters the cylinder near the bottom at which point it terminates in an open end 24. Located on this pipe line is a three-way valve 25 to one outlet oit' which is connected a pipe 26 which is laid to any desired point at which it is wished to draw oli water, being there provided with a valve or bibb 27.

In operation the three-way valve 25 is turned. so that communication is established between the pump and the cylinder' 12. ln this form it is also to be noted that a pipe 28 connects with the top of the cylinder being there iitted with a blow-oli valve 2.). In order to lill the cylinder the blow-oil' valve 29 is opened so that the water may rise in the cylinder. Then the blow-oilq valve 29 is closed and the pump operated. This forces air into the bottom ot' the cylinder and this air will rise through the water to the top of the cylinder formingr` as in the other case, a cushion of com pressed air. The three-way valve 25 is then turned to establish communication between the cylinder 12 and the pipe 26 thus cutting ofi' communication with the pump 15. The apparatus is now ready to deliver water and by opening the bibb 27 the water will VHow out oit it. t is readily understood that on proper manipulation or the valve 25 the pressure in the cylinder due to the pump 15 may be increased at any time in the emptying' of the cylinder and that the cylinder may be readily reiilled by opening the valve 29.

There has thus been provided a simple and eiticient device ot the kind described and 'l'or the purpose specified.

It is obvious that minor changes may be made in the torni and construction ot the invention without departing from the maA terial principles thereof. it is not ltherefore desired to coniine the invention to the exact form shown and described, but it is wished to include all such as properly come within the scope claimed.

ing :i check valve opening away from said 10 pump und a three-way Valve, a draw-ofi' pipe connected to said three-way Valve and provided wth an outlet bible, anda blow-off valve connected to the upper end of said Cylinder. p
